If you are not signed in with Facebook, your progress will not be saved to the cloud.
This means your save progress will be permanently deleted if you perform the following actions:
- Uninstall Castle Creeps TD
- Reformat your device
- Clear the App data from Castle Creeps TD through your settings menu
- Change your device
It is recommended to use the Facebook sign in to make sure you progress is safe, as this will allow you to recover your data at any time.
Logging in with Facebook will also allow you to play Castle Creeps TD on multiple devices, so the action never has to stop!
